I've been using Zaino products for several years, and have been very happy. Generally, AIO and multiple coats of z-5. I promised a friend that I would wax their car (a large SUV), and thought this might be a good time to go ahead and get a machine polisher - probably a PC UDM. Thinking I'd proably apply the products by had and remove with the machnie. Couple of questions. 1) Do I apply the Zaino by hand or with a machine? 2) What pads are the best for removal and application if I use the machine? 3) Is it really better to just keep doing it by hand? Thanks
